Hitoshi Mitake 0a7fc7cd34 etcdctl: add a new option --from-key for unlimited range permission
This commit adds a new option --from-key to the command etcdctl role
grant-permission. If the option is passed, an open ended permission
will be granted to a role e.g. from start-key to any keys those are
larger than start-key.

Example:
$ ETCDCTL_API=3 bin/etcdctl --user root:p role grant r1 readwrite a b
$ ETCDCTL_API=3 bin/etcdctl --user root:p role grant --from-key r1 readwrite c
$ ETCDCTL_API=3 bin/etcdctl --user root:p role get r1
Role r1
KV Read:
        [a, b) (prefix a)
        [c, <open ended>
KV Write:
        [a, b) (prefix a)
        [c, <open ended>

Note that a closed parenthesis doesn't follow the above <open ended>
for indicating that the role has an open ended permission ("<open
ended>" is a valid range end).
